<P>Hi,</P><P>&nbsp;</P><P>btm files are bootrom update files. Once bootrom has been updated, you can safely remove these files.</P><P>I was under the impression that 5120 always required manual bootrom update, but your experience seems to indicate that they have implemented the auto-bootrom update for the 5120 as well (which would be good news).</P><P>&nbsp;</P><P>Best regards,Peter.</P>Mon, 16 Dec 2013 19:49:42 GMThttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6306603#M4876Peter_Debruyne2013-12-16T19:49:42ZRe: A5120 Boot Rom an free flash spacehttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6307067#M4877
<P>I don't think so... We execute this command manually, so auto-bootrom update was not implemented jet, i think...</P><P>&nbsp;</P><P>1.

<P>As I understand you can safetly remove the .btm file once you have issued the bootrom update command and rebooted the device to make sure its (still) fully functional.</P><P>&nbsp;</P><P>As a sidenote: Since there is so little room available on the A5120 switches - whats the point of the main vs backup thingy when you only have room to only have one bin-file at a time in the flash?</P>Sat, 04 Jan 2014 19:09:37 GMThttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6322317#M4943Apachez-2014-01-04T19:09:37ZRe: A5120 Boot Rom an free flash spacehttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6327007#M5011
<P>To have more space for next bigger bin as example. To have space for debugging files or other useful files. But, out ov curiosity: if we can delete .btm files after upgrade, where the content of this file was placed ?&nbsp;as I said it's just a curiosity, it is not specified anywhere.</P>Tue, 07 Jan 2014 18:35:05 GMThttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6327007#M5011robyaps2014-01-07T18:35:05ZRe: A5120 Boot Rom an free flash spacehttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6327059#M5014
<P>I think you can see this bootrom as equal to the bios of a computer.</P><P>&nbsp;</P><P>Once flashed into the bios-chip the file can be removed from the harddrive.</P><P>&nbsp;</P><P>However the operatingsystem (bin-file) must remain on the harddrive (otherwise the device will fail to boot and only display the bootrom for you from where you can load the bin-file through xmodem or tftp or such).</P>Tue, 07 Jan 2014 19:21:53 GMThttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6327059#M5014Apachez-2014-01-07T19:21:53ZRe: A5120 Boot Rom an free flash spacehttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6329199#M5032
<P>Ok.</P><P>So these switches have an EPROM for the bios and flash as a local disk.</P><P>&nbsp;</P><P>The bootrom is the image of the bios that is temporary loaded on the DISK (FLASH) only to be placed in the BIOS (EPROM). Then "bootroom" file can be deleted from the disk, while the "bin" file (the operating system), of course to allow automatic start of the switch system, must reside on the DISK (FLASH).</P><P>&nbsp;</P><P>Thank you very much</P>Thu, 09 Jan 2014 10:34:04 GMThttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6329199#M5032robyaps2014-01-09T10:34:04ZRe: A5120 Boot Rom an free flash spacehttp://h30499.www3.hp.com/t5/Comware-Based/A5120-Boot-Rom-an-free-flash-space/m-p/6329237#M5033
